Hi there! I am trying to build a macOS app using Electron. There is a feature on the app that depends on a http server to run locally. This Server was built using Java.
Both the compiled server and the Java Runtime Environment were bundled in the build. To start the server I use NodeJS's child_process.spawn, pointing the bundled JRE's executable and the server implementation.
The issue I am facing is that the Java Virtual Machine is not starting. It returns the following error message:
Error: Port Library failed to initialize: -1
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Both the JRE and the server are located in Contents directory, in a subdirectory I have created for them.
Here are the app's entitlements:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.application-groups</key>
<string>REDACTED</string>
<key>com.apple.application-identifier</key>
<string>REDACTED</string>

<true/>
<key>com.apple.security.temporary-exception.files.absolute-path.read-write</key>
<true/>
</dict>
</plist>
Here the entitlements inherit:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.inherit</key>
<true/>
</dict>
</plist>
Is there any missing step to allow the spawning of this process?

Hi there! I am trying to publish a macOS app on App Store, thus the app must be sandboxed. The app is built with Electron and electron-builder. A tool of the app needs to run a local web server, to do so a java runtime and a .jar file are downloaded during runtime and the server is started using spawn.
In the MAS version of the app, running from TestFlight, I get EPERM error when spawn is called.
Both java's runtime and .jar are downloaded to app's container. I have tried also downloading them to outside the container (by saving them in the directories that are symlinked to outside of it) by I get the same error.
How could I solve that issue?
